Battlefield 3 | Mission 01 | SEMPER FIDELIS | Gameplay Walkthrough (No Commentary)
Semper Fidelis is the first mission in the single player campaign of Battlefield 3. The player, as Henry Blackburn, starts out in the middle of a New York City street overlooking a subway system. After hearing some police sirens, Blackburn dives onto the train, and barely manages to grab onto one of the car edges as he slides off the top. Blackburn then encounters Solomon behind an unbreakable window. He primes a set of explosive charges, and then walks away, whereupon Blackburn climbs out of the train and jumps from one car to the next, narrowly escaping the subsequent explosion. Solomon fires at Blackburn who stumbles and nearly falls onto the train tracks. However, he recovers, and manages to climb onto the top of the train. As he slowly advances, he is attacked by several operatives. Another explosion occurs on the car in front of Blackburn, allowing the marine to re-enter the train.
